Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives. In an article in the new issue of Regulation, Michael L. Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

McCain portrays himself as uniquely clear-eyed about the war. In fact, those eyes have often been full of stars. When Army Gen. Eric Shinseki forecast that more troops would be needed for the occupation, McCain didn’t fret. Shortly before the invasion, he said, “I have no qualms about our strategic plans.” As the online magazine Salon reports, he predicted the war would be “another chapter in the glorious history of the United States of America.”

He brags now that he criticized Donald Rumsfeld’s handling of the occupation. But McCain didn’t declare “no confidence” in him until a year and a half after the invasion. And let’s not forget the day he took a stroll through a Baghdad market, guarded by attack helicopters and 100 soldiers in full combat mode, to prove how safe Iraq was. The following day, 21 Iraqis were abducted from the market and murdered.

The point of the surge was to catalyze rapid progress that would facilitate our departure. But now the Pentagon says that come July, we’ll still have more troops than the 132,000 we had before. When Lt. Gen. Carter Ham was asked if the number will fall below 132,000 by the time Bush leaves office, he replied, “It would be premature to say that.”

McCain says the current “strategy is succeeding in Iraq.” His apparent definition of success is that American forces will stay on in huge numbers as long as necessary to keep violence within acceptable limits. We were told we had to increase our numbers so we could leave. Turns out we had to increase our numbers so we could stay.

Five years after the Iraq invasion, we’ve suffered more than 30,000 dead and wounded troops, incurred trillions in costs and found that Iraqis are unwilling to overcome their most basic divisions. And no end is in sight. If you’re grateful for that, thank John McCain.

As has always been the case, men like John McCain define leaving as losing and staying as success. If we stay in Iraq for 100 years, that’s “success.” If we leave, ever, we’ve lost.

I’d only add to Chapman’s column that, before the war, media darling St. John of Arizona was one of the most naive proponents of the “greeted as liberators” school of thought, assuring Larry King on September 24, 2002 that “I believe that the success will be fairly easy.” Five days later, McCain was back on CNN, assuring the American people that “I believe that the United States military capabilities are such that we can win a victory in a relatively short time. And I, again, I don’t think it’s, quote, ‘easy,’ but I believe that we can win an overwhelming victory in a very short period of time.” And so forth.

McCain’s claim to straight-talking rectitude on Iraq today is based solely on the fact that the Washington narrative has been changed as a result of The Surge. It’s almost as if it was designed to have just such an effect.
